GYCLOMETER AND REGISTER MECHANlSh".

SEEEQIFIGATIQN forming part of Letters Patent No. 695,536, dated March 18, 1902.

Application filed September 26, 1898. Renewed July 17,1901. Serial No. 68,682. (No model.)

To (LZZ whom, it may concern:

Be it known that I, LEO J. BUEDIOK, a citizen of the United States, residing at the city of Sturgis,in the county of St. Joseph and State of Michigan, have invented certain new and useful Improvements in Oyclometers and Register Mechanism, of which the following is a specification.

This invention relates to improvements in cyclometers and register mechanism. In certain particulars it is an improvement on the cyclometer for which I received Letters Patout No. 588,727, dated August 24,1807, and in other particulars it relates to an improved single-trip or detail mechanism for use with a total, whereby short distances or small amounts can be registered in connection with the total and the detail or single trip be returned to zero without interfering with the total distance or amount registered, my improvements being adapted for use on any register mechanism, though they are specially well adapted for use on cyclometers.

The objects of this invention are, first, to provide improved means of distributing the power to secure positive, even, and easy action of the number-wheels in a cyclometer or register; second, to provide improved stop means for the number-wheels of the cyclometer or register to prevent overregistration; third, to provide an improved internal gear with movable teeth for the initial mechanism for acyolometeror register; fourLh,to provide an improved single trip mechanism for a cyclometer or register; fifth, to provide an improved setback means specially adapted for single-trip cyclometer or detail register; sixth, to provide an improved ratchet means for use in a cyclometer or register mechanism .of the class described; seventh, to provide improved means of supporting the window in the case.

Other numerous objects will appear from the detailed description of the various parts of the mechanism in the specification.

I accomplish these objects of my invention by the mechanism and means described in this specification.

The invention is clearly defined and pointed out in the claims. T 1e structure and various modifications are fully illustrated in the accompanying drawings, forming a part of this specification, in which- Figure l is a vertical longitudinal detail sectional elevation of my improved register mechanism, taken on a line corresponding to line 1 1 of Figs. 2, 3, 4:, 5, and 6, adapted for use as a cyclometer Without any bracket or supporting means shown in connection, the View showing the structure much enlarged.

Fig. 10 is an enlarged detail perspective view of one ofthe number-wheels of the total-register mechanism. Fig. 11 is an enlarged detail perspective view of the rotating setback-cap with its speciallycoustructed spring-pawls for returning the single-trip or detail register to the zeropoint. Fig. 12 is an enlarged detail perspective view of a combined movable spring-tooth and internal gear for use in connection with the initial register mechanism. Fig. 13is an enlarged detail perspective view of the spring h and movable tooth h for efiecting the transfer in the total-register mechanism. Fig. 14 is an enlarged perspective view illustrating the arrangement of the numerals of the register. Fig. 15 is an enlarged detail view of the blank of which the spring-gear F shown in Fig. 12 is made. Fig. 16 is an enlarged detail perspective view of the spring-gear F after it is rolled into form.

In the drawings all of the sectional views are taken looking in the direction of the,1it tle arrows at the ends of the section-lines.

Similar letters of reference refer to similar parts throughout the several views.

Referring to the lettered parts of the drawings, A is the case, which is cylindrical in form, having a window consisting of a thin strip of celluloid t resting within the case on flanges at each side that are struck out there from. The inner end of the case is provided with a head A, which is secured rigidly in position by suitable screws, pins, or other means. This casing carries a star-wheel E on the outside and has a suitable ratchet-spring aon its hub, the whole being secured to the central shaft B of the cyclometer by the shouldered screw E. This extends through sleeves E on the gear E. This gear is one member of a hunting-tooth gear like that in my patent above referred to. The internal gear with which it meshes, however, is specially and economically formed from a strip of metal F, which is stamped out in the flat and rolled up,

one end F lapping over the other to form a spring and carrying the tooth F,which covers one of the apertures, to be pushed out by the projecting tooth on the gear E. The advantages are apparent, as it avoids the necessity of forming a separate spring and attaching it to the ring F,the whole being formed as easily as either of the single parts could be. The movable tooth F is forced out by the projecting tooth of the gear E and actuates the first number-wheel of the series, the same as in my former patent, above referred to, by engaging one ofthe internal gear-teeth. In this structure there are two separate register mechanisms on the same shaft, both of which are actuated from the single initial mechanism to which I have just referred. The total-register mechanism is on the portion of the shaft appearin g on the left on Figs. 1 and 9, and the single-trip mechanism appears tothe right-hand portion of the shaft appearing in Figs; 1 and 9.

The, right-hand portion of the shaft is sub-' cams formed upon it for the purpose of more evenly distributing, the power in the longer main register mechanism in transferring are like narrow transverse sections of the right-hand portion of the shaft, with the exception that the sections I are situated as though they had been turned exactly halfway around. The shaft can be in this form when made of a single piece. The hub of a number-wheel is exactly the width of two of these sections, and it carries upon it two springs h,with,.outwardly-projecting movable teeth h, which are supported one in the guide consisting of the lugs m m, (see Fig. 10,) and the other of which is supported on the opposite side in the guides 11. n on the opposite side of the wheel. Both of them-clasp the hub and rest side by side. From this description it will be observed that when any numberwheel is about to complete its revolution that the teeth on each side will be forced outwardly by passing onto the full portion of theshaft and will engage the internal gear-teeth on the next higher number-wheel on diametrically opposite sides, thus turning the same by a pressure evenly distributed around the shaft, greatly lessening the friction and securing a more perfect action.

The number-wheels of the single-trip portion are provided with only a single spring 9 and tooth g, located in a guide Z Z, similar to the other tooth-guides referred to. However, the guide Z Z does not extend the entire width of the hub, and a small spring f embraces the hub and has an inwardly-projecting portion or tooth f extending through a notch Z, diametrically opposite the guide for the movable tooth g, so that it engages in the vice surer and avoids the necessity of form-.

ing the small detaining-notch in the raised portion of the shaft.

The operation of both sections of the mechanism after the initial movement is secured v has thus been fully described.

Connected to the lowest wheel 0' of the main register mechanism is a lantern-like cylinder ordrum D, having longitudinal openings D at intervals, which serveas windows through which the numbers on the main number-wheels can be seen. The connection between this drum and number-wheelC is effected by little lugs or cars b, turned in from opposite sides of the cylinder D. The inner end of this cylinder D is formed with a projecting hub on it corresponding .to the hub of a number-wheel. On the hubof this drum is placed a spring Z Z, the end of which projectsoutside of the tooth-guide I I and into the guide from the outside, thus forming a ratchet for the actuation of the numberwhcels of the single-trip device whichwill IIO actuated by the same initial mechanism.

permit the first number-wheel of the same being returned to the zero-point without disturbing the position of the drum D. This consequently will allow the setting of the single-trip mechanism to the zero-point without disturbing the total-register mechanism. This structure fully appears in Fig. 4: of the drawings. The guidejj for this ratchet does not extend the entire width of the hub, but leaves room for the spring f. The hub has a notch K opposite the guidejj to serve as a locating and stop means on the shaft.

On the outside of eachnumber-wheel D of the single-trip mechanism is a thin plated band 6, bearing the numbers. The band D also has lugs e struck up therefrom. These little lugs could be formed in any well-known way on the exterior of the number-wheel; butthis method of covering the number-wheel and forming the lug is preferred by me, because the complete ring forms a perfectly smooth surface for the numbers, and the little lugs are easilystruck up from the same. Just outside the number-wheel is a circular drum G, open at one side corresponding to the window t', in the outer case. This is divided up into spring-pawls G (see Fig. 11) to act upon each of the number-wheels of the single-trip portion and engage the little lugs e to return the same to the initial position or zeropoint. It is preferred to divide this circular drum G into separate pawls for each number-wheel, because that secures an independent pawl of just sufficient strength to take care of the number-wheel and yet let it pass freely during registration, though 1 am aware that the device would be effectively operative without so dividing it. The drum or shell G is secured to the head A", and the head is pivoted at its center by the screw J to the center of the main shaft 13, so that the whole will freely rotate upon it. The end of the casing A fits into a rim on the head, so that it will easily revolve. The drum G fits closely in the outer casing and is prevented from accidental turning by friction at that place. WVhen it is desired to set the single-trip or detail portion at zero, all that is required with this device is to take hold of the end A of the casing and turn the same once around to the right, when all of the spring-pawls G will have at some point during their passage engaged the lugs e and returned each separate number-wheel tothezero-point. Thenumber-wheelD,next to the drum D, passes very readily over the spring 5 like a ratchet, the trip or distance traveled will be registered up to the limit of the single-trip device, and the whole will also be registered on the total-register mechanism, because that is not disturbed by setting the single-trip device back to zero, and both are In this connection I desire to state that the drum D could be made of transparent material, as celluloid or glass or the like, and serve the same purpose as this drum D, with slots for the windows. The ratchet between the parts could be otherwise constructed, though the form I have adopted is superior on account of its simplicity and ease of construction. The set-back mechanism can also be greatly modified. Numerous other variations will no doubt occur to those skilled in the art to which my invention pertains. I have illustrated only one form in this connection, which is the best for many reasons.

The set-back mechanism might be utilized in other styles of cyclometers where the transfer between the numbers is effected by other means than those here shown, though of course there is a special relation and a special adaptation of the several parts of the structure here appearing. WVith regard to the special construction of the main registering mechanism I would respectfully state that while two actuating-springs and teeth on the hubs will be sufficient under all ordinary circumstances, yet under certain conditions and large sizes it may be desirable to form the shaft with more than two sections for each hub with correspondingsprings and teeth distributed at closer intervals than opposite to each other. These features will be so clear to the skilled mechanic that further illustration is not necessary. The same distribution of springs and engaging teeth is employed. I have only shown the one form for the rea sons before stated, but add this statement to show that I realize and fully understand the possibilities of the invention which is given a special embodiment in the drawings herewith presented. The structure is here shown in the best and most practical form for a cyelometer,though in practice some slight modifications andimprovements in the details may be developed. Other forms may be required for other styles of register mechanism.
